Este circuito tiene la función de controlador para cuatro circuitos de tiras de luces LED múltiple, donde se usarán convertidores reductores, ya que es el mas simple de los controladores de conmutación (tipo Buck) y en este circuito esta aplicado ya que el voltaje de la carga nunca supera el 85% del voltaje de la alimentación y es capaz de regular la potencia AC de entrada y convertirlo para los 4 voltajes de salidas en DC, con el objetivo de alimentar las 4 tiras de luces LED. Este circuito convertidor reductor generalmente usa un MOSFET de potencia para cambiar el voltaje de alimentación a través de un inductor y las cargas que son las tiras de luces LED en serie. El inductor se utiliza para almacenar energía cuando se enciende el MOSFET, está esta energía se utiliza para proporcionar la corriente a las tiras de luces LED (las cuales tienen un consumo de 350 mA) cuando se apaga el MOSFET. Un diodo a través de las tiras LED y el circuito proporciona una ruta de retorno para que la corriente durante el tiempo de apagado del MOSFET.

Build your own Modular LED Sign! This design prioritizes accessibility which means that the BoM can be ordered on Amazon and that everything was designed with solder-ability in mind. NOTE: This board is still an unfinished prototype that has not been built and verified. Operating Instructions: 1. [Important!] Power your buck converter and adjust the output voltage to 1.5V output before attempting to power the LEDs. If you cannot power the buck converter, just turn the potentiometer counterclockwise to its maximum setting.
